Lineage: Rhodospirillum centenum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Rhodospirillum centenum, also called Rhodocista centenaria, is a nitrogen-fixing photoheterotroph with a complex life cycle. R. centenum is one of the few known thermotolerant purple bacteria species with optimal growth temperature of 44 dgrees C and a maximal growth temperature of 48 degrees C. In liquid media this organism is motile by a single polar flagellum. R. centenum produces lateral flagella to become a swarming cell. Under low nutrient conditions R. centenum forms a desiccation- and UV-resistant cyst. R. centenum can often be cultivated from hot springs such as those found at Yellowstone National Park. R. centenum is emerging as a model organism for genetic and molecular genetic analysis of cyst formation.
Subject: NC_014760:299392 Mycoplasma bovis PG45 chromosome, complete genome
Lineage: Mycoplasma bovis; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: This bacterium causes a contagious disease of cattle causing respiratory disease, mastitis, and arthritis. It is found worldwide and is inherently resistant to certain groups of antibiotics because it does not possess a cell wall. More recently, this species has become resistant to tetracycline, tilmicosin and spectinomycin which have been traditionally used in its control. The disease is spread between herds by the transfer of infected but seemingly healthy animals which shed viruses. It has also been introduced into healthy herds via frozen semen collected from an infected bull. The economic losses and negative impact on international trade from this disease have been considerable, and efforts are now underway to develop a vaccine.
